Hi all,
I've just taken delivery of two of these, and although the instructions are only in German, I am getting to grips with them.
The only problem I have is with the 16-pin IC sockets - because there are only 14 holes!
I'm trawling my way through the instructions but haven't been able to find out how to install the sockets onto the circuit board - or to determine which pins to cut off.
While I'm waiting for Viessmann to respond, has anyone else used this kit and resolved the question?
Thank you,
Pete |

Hi Pete,
if the IC (Integrated Circuit) has only 14 pins, buy a 14 pins IC socket and solder it, otherwise something is wrong with the PCB and so ask Viessman.
I am not able to give other suggestions, as I do not have a 5290 kit.
Bye
Renato

Ah, would it be that easy!
No, both the socket and IC have 16 pins. The circuit board is the same as the diagram and the parts list states it's 16 pins.
Viessmann haven't responded so I'll have to wait until next week now and see what they say.
Thank you,
Pete

Well, not having in my hands neither the electric diagram nor the PCB, I think two holes have not be drilled.
If Viessman will not give you an answer, having a scan of the electric diagram, both sides of the PCB and the components list, I could (not 100% sure!) help you and say which holes have to be drilled.
Bye

OK, I'm a plum!
The IC sockets have 16 pins but the IC's themselves only have 14 pins.
I could buy 20 of these sockets from eBay for £2.70 all-in, so I'm tempted to do that. Unless I can get away with cutting the pins off, as I previously considered. It doesn't sound very professional, though!

Pete I also had this in two of my Viessmann kits, I happened to have some 14 pin sockets on hand though and used them. http://layout.mixmox.com/1/Viessmann-5291_kitcut off two pins. |
